mplate element. It provides a quick \n * and easy way to do data binding without
the need to setup a model. \n * The `auto-binding` element itself serves as the
model and controller for the \n * elements it contains. Both data and event han
dlers can be bound. \n *\n * The `auto-binding` element acts just like a templat
e that is bound to \n * a model. It stamps its content in the dom adjacent to it
self. When the \n * content is stamped, the `template-bound` event is fired.\n *
\n * Example:\n *\n * <template is=\"auto-binding\">\n * <div>Say some
thing: <input value=\"{{value}}\"></div>\n * <div>You said: {{value}}</div
>\n * <button on-tap=\"{{buttonTap}}\">Tap me!</button>\n * </template
>\n * <script>\n * var template = document.querySelector('template');\
n * template.value = 'something';\n * template.buttonTap = function(
) {\n * console.log('tap!');\n * };\n * </script>\n *\n * @mod
ule Polymer\n * @status stable\n*/\n\n(function() {\n\n var element = document.

dom adjacent to itself. When the \n * content is stamped, the `template-bound` e

<div>Say something: <input value=\"{{value}}\"></div>\n * <div>You sa
id: {{value}}</div>\n * <button on-tap=\"{{buttonTap}}\">Tap me!</button>\
